All I can say is that the pistol permit department in my county notified me that I could no longer allow students to handle handguns during training. That was two or three years ago. I keep a copy of my certification in their office and they notified all instructors. My local gun shops will no longer let you handle handguns without a permit. I don't know the dates of the info you posted but maybe something has changed and the posting is not updated. You might want to check with your local handgun permit office. Thanks for the info though.
I have some dummy guns I use during training.
